A winding device for producing a field coil including a double-layer multiple-circuit winding for an electric motor includes a drive. The drive is configured to operate upon a winding mandrel with multiple lamellas arranged to be swung radially outwardly and inwardly by the drive in order to produce the double-layer multiple-circuit winding as a plurality of winding stacks that are arranged in separate slots and electrically connected in series, in parallel or both. At least two axially-separated winding stacks can be produced at the same time by the drive.

The commutating poles of vehicular-type dc motors, for example for trolley buses or trolley cars, are made by winding, on edge, a copper strip, permitting the wound copper strip to resiliently, spring-like expand so that the individual spiral loops thereof will be slightly spaced from each other, and then exposing the copper strip in a fluidized bed to an insulating powder, for example polyethylene or polyurethane, which is subsequently cured in a hardening or sintering process.

Process of making a dynamo electric machine

The stator of a three phase AC generator is wound automatically. A first set of partial windings consitutes the first winding. Each of the partial windings has at least one turn. The first partial winding is wound in slots 1 and 4 in the clockwise direction, the second in slots 7 and 4 in the counterclockwise direction, etc. Before the second partial winding of the first set is wound, the first partial windings of the second and third phase are wound in slots 2 and 5 and 3 and 6, respectively. Similarly, after the counterclockwise winding in slots 4 and 7, the second partial windings of the second and third phase are wound in the counterclockwise direction in slots 8 and 5 and 9 and 6, respectively. This procedure is repeated until all slots are filled. If the same winding profile is to be maintained throughout, the part of the first partial windings associated with the first, second and third phase to be inserted in slots 1, 2, 3, respectively, is left out of the slots until the last partial winding of the phases has been wound. The loose ends of the first partial windings are then pushed into the respective slots. After the partial windings are connected to each other to form the first, second and third main windings, the winding starts and the winding ends of these main windings are connected together to form the desired electrical configuration. In this connection, the start and end of the second winding are electrically interchanged, to create the required 120.degree. phase difference between all the windings.
